PARK CITY, Utah – There are a few things the normally loquacious Jodie Foster doesn’t like to talk about – her private life and “Hannibal,” for starters.

She was friendly and polite but made it clear she was at the Sundance Film Festival – which ended yesterday – to talk about “The Dangerous Lives of Altar Boys,” a pet project she produced and stars in – as a one-legged motorcycle-riding nun.

Most know better than to ask this intensely private single mom about the paternity of her two sons, Charles, 3, and Kit, 4 months.

But Foster won’t even say whether she’s seen “Hannibal,” in which Julianne Moore took over Foster’s Oscar-winning role as FBI agent Clarice Starling from “The Silence of the Lambs.”

“I won’t talk about that,” she said firmly.

The Yale University grad turned down a $10 million paycheck for “Hannibal,” reportedly because she had reservations about the ultra-grisly script – prompting its producer, Dino De Laurentiis, to offer this nasty assessment of Foster’s sex appeal:

“As an audience . . . I see Julianne Moore, and I want to go to bed with her. I see Jodie Foster, and no way.”

Foster may not want to talk about that, but she did deny recent reports that her long-planned biography of notorious Nazi filmmaker Leni Riefenstahl, who turns 100 this year, will go before the cameras later this year.

And she did talk briefly talk about her son, Kit, who was born in September – while she was shooting the thriller “The Panic Room,” due out in March. In it she plays a woman hiding from intruders with her young daughter in a Manhattan brownstone.

“Two kids are a handful, and so was that movie,” the diminutive 39-year-old actress said with a laugh.

“I managed to get pregnant, be pregnant, give birth and still not be finished with that movie. . . . But I’m really, really happy with the way it turned out.”

Her other baby – the reason she returned to Sundance for the first time since she was a juror in the ’80s – was a more difficult delivery.

Through her Egg Pictures, Foster produced “The Dangerous Lives of Altar Boys,” in which she plays a nun who works with troubled adolescents at a Georgia parochial school.

“Altar Boys” was set to premiere at last year’s Sundance festival. It was pulled at the last minute because of delays in completing complex and striking animated sequences devised by Todd McFarlane, creator of “Spawn.”

The film was later offered for a premiere at the Cannes Film Festival, which passed on it.

Some saw it as a deliberate snub of Foster – who had just dropped out as head of the Cannes jury to replace Nicole Kidman in “The Panic Room.”

“I was the one person who never believed that,” she said, with a chuckle, of the supposed slight.

“But I believe all things happen for a reason, and once Cannes didn’t happen, we realized Sundance was the right place to premiere. And the organizers there were great about inviting us again.”
